Application filed November 16, 1927.

The object of my invention is to provide a sweater having sleeves so reinforced as to have superior wearing qualities along that longitudinally extending part of the sleeve which extends over the elbow and which, when the sleeves are laterally extended from the body, forms the back or under part of the sleeve.

In the accompanying drawings, which .1llustrate a preferred embodiment of themvention and indicate the means of providing such reinforcement1 Fig. l is a front view of a sweater embodying my invention.

Fig. 2 is a side view, and Fig. 3 an edge View or cross-section, of a tubular piece of fabric from which the sleeves are formed.

Fig. 4 is a section through a sleeve on the line 4 4 Fig. l.

A tubular fabric, wherein the courses eX- tend circumferentially, is knit., preferably on a circular machine in which the knitting cylinder rotates. During each complete rotation of the cylinder, an extra reinforcing thread (or a series of threads if the machine has a plural yarn feed) is fed to the needles at the Wale a and is withdrawn from feeding position at the Wale b; and is again fed to the needles at the Wale c (diametrically opposite a) and again withdrawn at the Wale d (diametrically opposite b). Thus is formed a tubular fabric e provided, in opposite halves, with longitudinally extending, diametrically opposite reinforcing strips or sections f, g.

The fabric is then cut, on a line longitudinally along each reinforcing section to form two separate pieces of flat fabric and the severed edges of each piece are secured together to form a seamed tube constituting a sleeve y of the sweater. The opposite ends of the line x along which the fabric is cut, as shown in Fig. 3, are on opposite sides of a longitudinal line exactly bisecting the reinforced section, line m intersecting such longitudinal center lin-e midway of its length. The opposite ends of the cutting line, which preferably has a compound curve contour more or less like that shown, are symmetrical and divide the reinforced section into two subsections of equal area, each, however, tapering in width from one end of the fabric to SWEATER.

the other. The cutting lines of the two halves of the fabric (as those halves are shown in Figure 3) are coincident, when those halves are viewed as in Fig. 2, thereby forming two flat pieces which are relatively wide at one end and relatively narrow at the other. Each severed strip is therefore composed of a central non-reinforced section of uniform width and edge reinforced sections which taper in width from one end to the other.

When each piece is sewed along its opposite longitudinal edges to form the ultimate tubular fabric 1 such tube tapers in diameter and is provided with a non-reinforced longitudinally extending section of uniform width and a reinforced longitudinally extending section tapering in width from one end toward the other while the seam z extends through the longitudinal center of the tapered reinforced section.

The tubes y form the sleeves of the sweater and the ends thereof of reater diameter are sewed to the body w of the sweater. The sleeves are so Secured to the body that the seam e and the reinforced section extend along the back or under part of the sleeve from its shoulder end to its cuff end.

Having now fully described my invention, what I claim and desire to protect by Letters Patent is:

1. A tubular blank of knitted fabric from which a pair of sleeves can be cut, having two oppositely disposed longitudinally extending reinforced strips between twolongitudinally extending strips which have not been reinforced, adapted to be out along each reinforced strip to form two sleeve blanks, each of which can be secured together along the cut edges to form two sleeves, with a reinforced portion on each side of the seam.

2. The method of forming reinforced sleeves for sweaters, comprising knitting a tube with two oppositely disposed reinforcing strips extending longitudinally thereof, then cutting the tube into two blanks along the reinforcing strips between the edges thereof, and then seaming together the severed edges of each piece to form a sleeve.

In testimony of which invention, I have hereunto set my hand, at Philadelphia, Pennsylvania, on this 11th day of November, 1927.

GEORGE GRUSHLAW.
